Weston A. Thelen, Alicia J. Hotovec-Ellis, Paul Bodin
2016, Open-File Report 2016-1172
The effects of earthquake shaking on the population and infrastructure across the State of Hawaii could be catastrophic, and the high seismic hazard in the region emphasizes the likelihood of such an event. Earthquake early warning (EEW) has the potential to give several seconds of warning before strong shaking starts,...

Trevor J. Hefley, Mevin Hooten, John M. Drake, Robin E. Russell, Daniel P. Walsh
2016, Ecology Letters (19) 1353-1362
Inferring the factors responsible for declines in abundance is a prerequisite to preventing the extinction of wild populations. Many of the policies and programmes intended to prevent extinctions operate on the assumption that the factors driving the decline of a population can be determined. Exogenous factors that cause declines in...

Development and assessment of a new method for combining catch per unit effort data from different fish sampling gears: Multigear mean standardization (MGMS)
D.K. Gibson-Reinemer, Brian Ickes, John H. Chick
2016, Canadian Journal of Fisheries and Aquatic Sciences (74) 8-14
Fish community assessments are often based on sampling with multiple gear types. However, multivariate methods used to assess fish community structure and composition are sensitive to differences in the relative scale of indices or measures of abundance produced by different sampling methods. This makes combining data from different sampling gears...

Nathaniel Mikle, Tabitha A. Graves, Ryan P. Kovach, Katherine C. Kendall, Amy C. Macleod
2016, Proceedings of the Royal Society B: Biological Sciences (283)
Current range expansions of large terrestrial carnivores are occurring following human-induced range contraction. Contractions are often incomplete, leaving small remnant groups in refugia throughout the former range. Little is known about the underlying ecological and evolutionary processes that influence how remnant groups are affected during range expansion. We used data...
